NEW YORK — Polymarket and Kalshi, prediction markets on which users can bet on outcomes as varied as the Super Bowl and the length of the State of the Union address, have been some of the fastest growing destinations on the internet.

The company may be seeking to compete with Polymarket and Kalshi.

Mark Zuckerberg directed Meta to build a prediction market app called Arena that would compete with Polymarket and Kalshi, the New York Times reported.
